The goal is to cut the time spent on ancillary training to the “minimum level necessary,” Air Force Chief of Staff Gen. Michael T. Moseley was quoted as saying in an Air Force news release Monday.

Under the new policy, the Air Force will cluster the training into a 90-minute “block instruction” plan. Commanders will have the option to hold the entire 90 minutes in one mass briefing, or split it into three segments throughout the year, according to Air Force officials.
